[PATCH net-next v5 0/2] net sched actions: improve action dump performance

[Jamal Hadi Salim]

From: Jamal Hadi Salim <j...@mojatatu.com>

Changes since v4:

1) Eric D.

pointed out that when all skb space is used up by the dump
there will be no space to insert the TCAA_ACT_COUNT attribute.

2) Jiri:

i) Change:

enum {
        TCAA_UNSPEC,
        TCAA_ACT_TAB,
        TCAA_ACT_FLAGS,
        TCAA_ACT_COUNT,
        TCAA_ACT_TIME_FILTER,
        __TCAA_MAX
};

#define TCAA_MAX (__TCAA_MAX - 1)
#define ACT_LARGE_DUMP_ON               (1 << 0)

to:
enum {
       TCAA_UNSPEC,
       TCAA_ACT_TAB,
#define TCA_ACT_TAB TCAA_ACT_TAB
       TCAA_ACT_FLAGS,
       TCAA_ACT_COUNT,
       __TCAA_MAX,
#define        TCAA_MAX (__TCAA_MAX - 1)
};

#define ACT_LARGE_DUMP_ON              BIT(0)

Jiri plans to followup with the rest of the code to make the
style consistent.

ii) Rename attribute TCAA_ACT_TIME_FILTER --> TCAA_ACT_TIME_DELTA

iii) Rename variable jiffy_filter --> jiffy_since
iv) Rename msecs_filter --> msecs_since
v) get rid of unused cb->args[0] and rename cb->args[4] to cb->args[0]

Jamal Hadi Salim (2):
  net sched actions: dump more than TCA_ACT_MAX_PRIO actions per batch
  net sched actions: add time filter for action dumping
